Our results support increased transcription of retrotransposons in transformed cells, which may explain the somatic retrotransposition events recently reported in several types of cancers. (nih.gov)
We have characterized a panel of somatic cell hybrid cell lines which contain different portions of human chromosome 10. (ncsu.edu)

It is likely that chromosome 10p12.1-p13 may harbor a maturity-onset diabetes of the young or type 2 diabetes gene. (diabetesjournals.org)

This initiative, called the Human Cell Atlas, proposes to create comprehensive reference maps of all human cells as a basis for both understanding human health and diagnosing, monitoring, and treating disease. (genengnews.com)

Chromosome 12 likely contains 1,100 to 1,200 genes that provide instructions for making proteins. (medlineplus.gov)

They found that during evolution, a reshuffling of DNA known as translocation brought together separate chunks of sex-determining genes onto a single chromosome, essentially mimicking the human X or Y chromosome. (phys.org)
The most common translocation that causes this condition fuses part of the PDGFRB gene from chromosome 5 with part of the ETV6 gene from chromosome 12, written as t(5;12)(q31-33;p13). (medlineplus.gov)
The image shows chromosomes from a cancer patient, showing 2:3 translocation. (lu.se)

Fluorescence "in situ" hybridization (FISH) technique enables chromosomes to be tagged with fluorescent dyes to highlight genetic traits. (lu.se)

In head and neck cancer, tobacco exposure and alcohol consumption are predominantly the most significant external factors for tumor formation. (bvsalud.org)
Tobacco and alcohol exposure are two main etiological agents as in concern to head and neck cancer. (bvsalud.org)
Despite the risk of tobacco and alcohol exposure, the majority of patients who smoke or drink alcohol do not develop oral cancer. (bvsalud.org)

Three steps are described in the development of cancer namely initiation, promotion and progression. (bvsalud.org)

These regions of the chromosome are so dense that they were once thought to be removed from recombination. (phys.org)
Thus, the IBD mapping results can be further supplemented by removing any regions that are identical in both affected individuals and unaffected siblings. (wikipedia.org)
Chromosomes are made up of genes and regulatory regions - switches that determine when and where the genes turn on and off - linked arm in arm like the setup for the childhood game of Red Rover. (stanford.edu)
The panel of hybrid cell lines is thus useful for rapidly localizing unmapped probes and as a source of DNA for the construction of recombinant libraries derived from specific regions of the chromosome. (ncsu.edu)

Characterization of radiation/fusion hybrids containing parts of human chromosome 10 and their use in mapping chromosome 10-specific probes. (ncsu.edu)
Hybridization of an unmapped probe to the cell line DNAs can be used to determine its most likely position on the chromosome relative to the mapped set of probes. (ncsu.edu)
Several of these probes reveal restriction fragment length polymorphisms which have been genetically mapped. (ncsu.edu)
Fixed bugs include errors in documentation (default has never been to remove cnv probes), handling of when there are no probes for entire chromosomes, and 'split_samples.pl' can now handle language settings for which !BeadStudio generates files in which comma denotes the decimal point. (lu.se)

He has spent over 30 years studying various aspects of the changes to chromosomes that lead a cell to change and develop into a cancer cell, with a particular focus on leukaemia. (lu.se)

However, there are no reliable tools to decipher the molecular composition of metaphase chromosomes. (monash.edu)
Here, we have applied infrared nanospectroscopy (AFM-IR) to demonstrate molecular difference between eu- and heterochromatin and generate infrared maps of single metaphase chromosomes revealing detailed information on their molecular composition, with nanometric lateral spatial resolution. (monash.edu)
Background: The molecular events leading to the development of ovarian cancer are not well-established. (iiarjournals.org)

Regardless of the name or species, Heitman contends that some universal principles could govern the evolution of all sex chromosomes. (phys.org)
